Answer:
0.0078125
Step-by-step explanation:
Probability of tail, p = 0. 5
Probability of getting all tails from 7 tosses :
P(tail) * P(tail) * P(tail) * P(tail) * P(tail) * P(tail) * P(tail)
0.5 * 0.5 * 0.5 * 0.5 * 0.5 * 0.5 * 0.5 = 0.0078125
We could also use the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - r)
n = 7 ; x = 7, p = 0.5,
P(x = 7) = 7C7 * 0.5^7 * 0.5^0 = 0.0078125
Answer:
A
Step-by-step explanation:
Answer:
I will do a step by step explanation to help you.
First, subtract 16 from 31 so you can simplify what you need to find. We will call the unknown number X. So 5x = 15
15/5 = 3 so X = 3
Lets plug in X
3 x 5 + 16 = 31
Makes sense!
Hope this helps
<span>To catch him in 15 minutes the father must travel 32 miles per hour faster (since 1/4 hr * 32 mph = 8 miles)...
Thus the father must drive at 40 miles per hour. </span>
