5 striped shirts,
6 solid shirts,
2 floral,
2 polka dot.

Respuesta :

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.
