Its is equal to 21 because 3x3 is 9 42/7 is 6 then 6+6=12 so then 9 +12=21
Well it says t= 5 so you literally put 5 in for t into the equation to get y
Answer:
b. 3 + (p x 6)
Step-by-step explanation:
i hope this helps :)
12 cause that is the max amount of girls and there is no other way to get the groups even if you go over.
Let event A be the first light being red.
Let event B be the second light being red.
P(A) = 0.48
P(A & B) = P(A) * P(B) = 0.35
P(B) = 0.35 / P(A)
P(B) = 0.35 / 0.48
P(B) = 0.73
Since the lights are independent, P(B|A) = P(B) therefore d is the correct answer.
