P(head) = 1/2 = 50%
P(tail) = 1/2 = 50%
Answer:
Step-by-step explanation:
7x+10x-50=69
17x=69+50
x=7
The answer to your question is 2.47
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} = 
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) =
