A bowl contains 7 white pebbles and 5 black pebbles. A pebble is chosen and not replaced, then another pebble is picked. What is the probability that the first one is a white pebble and the second one a black pebble?

Answers

Answer:

35/132

Step-by-step explanation:

7 white pebbles, 5 black pebbles

7 + 5 = 12

12 pebbles total

First drawing:

p(white) = 7/12

Second drawing:

The white pebble was not replaced, so the total now is 11 pebbles.

p(black) = 5/11

p(white then black) = 7/12 * 5/11 = 35/132

The probability that the first one is a white pebble and the second one a black pebble is 26.51%.

What is probability?

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

A bowl contains 7 white pebbles and 5 black pebbles. A pebble is chosen and not replaced, then another pebble is picked.

Then the probability that the first one is a white pebble and the second one a black pebble will be

Total event = 12

Number of the white pebbles = 7

Number of the black pebbles = 5

Then the probability will be

[tex]\rm P = \dfrac{7}{12} \times \dfrac{5}{11}\\\\P = \dfracd{35}{132}\\\\P = 0.2651 \ or \ 26.51\%[/tex]

Two angles are supplementary. One has a measure of 25 degrees. What is the measure of the other angle

90 degrees
65 degrees
23 degrees
155 degrees

Answers

Answer:

155 degrees

Step-by-step explanation:

supplementary angles add up to equal 180°

To find an angles supplement we can subtract the measure of the given angle ( 25 ) from 180

180 - 25 = 155

Hence, the measure of the other angle is 155 degrees

Answer:

Its either 65 or 155 depending if supplementary is 180 or 90.

Answers

Step-by-step explanation:
GIVEN: Two digit number means we will have to choose from numbers 0-9 for the second digit and 1-9 for the first digit. (since zero can't be in the tens place)
Formula: We will use m x n. That is, m is the number of elements we can use for the first digit and n will be the number of elements we can use for the second digit.
Sample Space: To get the probability, we must find the sample space or all the outcomes.
m - 9 elements (1-9)
m - 9 elements (1-9)n - 10 elements (0-9)
m x n = 9x10 =90
90 is our sample space.
A. An odd number
Conditions: For an odd number, the second number will determine whether or not it is an odd number. For the first digit, we can use 1-9.
Elements:
m - 9 elements (1-9)
m - 9 elements (1-9)n - 5 elements (1,3,5,7,9)
m x n=9x5=45
SOLVE (probability)
Probability= possible outcomes/sample space
P=45/90
P=1/2
B. Larger than 75.
Conditions: The first digit could be equal to 7 or greater. But n will only be greater than 5 if and only if m=7 and n could be any number if m>7.
Elements 1:
m - 1 element (7)
m - 1 element (7)n - 4 elements (6,7,8,9)
m - 1 element (7)n - 4 elements (6,7,8,9)m x n=1x4=4
Elements 2:
m - 2 elements (8,9)
m - 2 elements (8,9)n - 10 elements (0,1,2,3,4,5,6,7,8,9,)
m - 2 elements (8,9)n - 10 elements (0,1,2,3,4,5,6,7,8,9,)mxn=2x10=20
TOTAL: 4+20=24
SOLVE (PROBABILITY)
Probability= possible outcomes/sample space
P=24/90
P=4/15
C. multiple of 5
Condition: the second digit must be either 0 or 5 and the first digit could be any digit.
Elements:
m - 9 elements (1-9)
m - 9 elements (1-9)n - 2 elements (0,5)
m x n =9x2=18
SOLVE (PROBABILITY)
P=18/90
P=1/5
D. An even number smaller than 40
Condition: The first digit could be equal to 4 but the second digit must be even (excluding zero). Another situation is the first digit would be greater than 4 and the second digit would be any even number.
Elements 1:
m - 1 element (4)
n - 4 elements (2,4,6,8)
m x n = 1x4=4
Elements 2:
m - 5 elements (5,6,7,8,9)
n - 5 elements (0,2,4,6,8)
mxn=5x5=25
TOTAL: 25+4=29
SOLVE: Probability
P=29/90
