Alex has 5 tshirts in the drawer. 2 are white, and the rest are black. he will pick a t-shirt from the drawer without looking, and then without replacing it, will pick a second t-shirt without looking. what is the probability that he will pick a white t-shirt on his first pick and a black t-shirt on his second pick?

Probability

Step-by-step explanation:

Number of T-Shirts

White T-Shirts

Black T-Shirts

Probability of First White T-shirts:

Number of White T-Shirts

Hence Favourable outcomes

Total Outcomes

Probability of Second Pick is black:

Remaning T-Shirts

So total outcomes

Favourable outcomes

These two events are independent, So the probability that first pick is white and second is black

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
