Answer:
2/45
Step-by-step explanation:
First chooses a polka dot shirt: 2 / (5+6+2+2) = 2/15
Then a striped shirt, after replace: 5/15 = 1/3
the probability that she chooses a polka dot shirt then a striped shirt:
2/15 x 1/3 = 2/45
The probability of choose a polka dot shirt then a striped shirt in total type t shirt is 2/45
Probability:
Probability is a mathematical possibility and is calculated as the ratio of favorable outcomes to the total number of outcomes of any event.
How to calculate probability ?
Here we have given that the type of t shirts are
5 stripped, 6 solid, 2 floral, 2 polka therefore total types are 5 + 6 + 2 + 2 = 15
The probability of choose a polka is = 2/ 15
Also the probability of choose stripped shirt after replace = 5/15 = 1/3
Therefore
The probability of choose a polka dot shirt then a stripped shirt is
= 2/15 x 1/3 = 2/45
This is the final answer.
