In the laundry basket there are 4 black socks, 7 pink socks, and 10 white socks. Allison will randomly select 2 socks from the basket one at a time without replacement. What is the probability that Allison will select 2 pink socks?

Step-by-step explanation:

Given: In basket, we have

4 black socks, 7 pink socks, and 10 white socks.

Total socks = 4+7+10 = 21

Probability that first sock is pink =

Now basket has 6 pink socks left and total socks left= 20

Probability that second sock is pink =

The probability that Allison will select 2 pink socks =

Hence, the probability that Allison will select 2 pink socks =

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
