Answer:

Step-by-step explanation:

B)  S = {1,2,3,4,5,6}

n(S) = 6

B =  factors of 2 when rolling a single die = {1 , 2}

n(B) = 2

P(B} = [tex]\frac{2}{6}=\frac{1}{3}[/tex]

A) n(S) = 50

A  = Picking numbers with 3 in tens place = {30, 31,32,33,34,35,36,37,38,39}

n(A)  = 10

P(A) = [tex]\frac{10}{50}=\frac{1}{5}[/tex]
