Let's start with the Promising Probability section :)

A box contains 2 green balls and 5 yellow balls.
Two balls are drawn at random without replacement.
If the first ball drawn is green, what is the probability the second ball is yellow? This question is required.

Billy's drawer contains 5 blue socks and 6 black socks.
Billy pulls out two socks at random without replacement.
If the first sock drawn is black, what is the probability the second sock is also black and Billy has a pair?

See below the formula to convert degrees Fahrenheit (F) to degrees Celsius (C):
C = 5/9 (F – 32)
What is the value of C when F = 77?This question is required.

If a = 3, then what is the value of 7 + 5a?This question is required.
