ASAP HELP PLZZZZZ
Hasan has a bag of 25 counters. 15 of the counters are black. 10 of the counters are white. hasan works out that the probability of picking two counters is (2/5)²=4/25 what assumption has hassan made for this probability to be true?

Answer 1

Given,

There are a total of 25 counters

15 of the counters are black.

10 of the counters are white

 

Hasan calculates the probability of picking two counters to be (2/5)^2 = 4/25

For this probability to be true, Hasan has made the assumption that he would pick two white counters consecutively.

 

Probability of picking two white counters consecutively

= (10/25) * (10/25)

= (10/25)^2

= (2/5)^2

= 4/25
