Answer:
0.0512
Step-by-step explanation:
Probability of making a correct guess ; p = 1 / 5 = 0.2
q = 1 - p = 1 - 0.2 = 0.8
Number of questions, n = 5
Using the binomial probability relation :
P(x = x) = nCx * p^x * q^(n-x)
P(x = 3) = 5C3 * 0.2^3 * 0.8^2
P(x = 3) = 0.0512
Answer
Work:
Volume is total = 8460 in3
Width 40in
Height 9in
Length?
Formula v/(w x h)
40 x 9 = 360
8460 / 360 = 24in
Length is 23.5 in
