MrRissso [65]

Scott is 62+3=65 inches tall, and there are 12 inches in a foot, so you get 65/12=about 5 whole feet. 5 whole feet is 60 inches in total, so we have a leftover 5 inches, meaning that Scott is 5 feet and 5 inches tall.

A bowl contains 25 balls numbered 1 to 25. A ball is drawn and its number is noted. Without replacing the first ball, another ba

Afina-wow [57]

Step-by-step explanation:

n(S) = 25

Assume that O : odd numbers and E : even numbers,

n(O) = 13

n(E) = 25-13 = 12

P(OO) = P(O) x P(O)

= 13/25 x 12/24

(because without replacing so the number of balls left decreases)

= 13/25 x 1/2

= 13/50
