Answer:
So, the probability is P=0.0135.
Step-by-step explanation:
We know that at a certain airport, 65% of the flights arrive on time.
We get that p=0.65 and q=1-0.65=0.35.
We have 10 flights, so n=10.
We calculate the probability that all 10 of the flights were on time, so k=10.
We use the formulu:
we get:
So, the probability is P=0.0135.
Answer: 8 ft and 4 in, 8 1/3 ft
Step-by-step explanation:
100/12=50/6=25/3=8.3333333...
1/3 of a foot is 1/3x12 which is 12/3 which is 4 in.
Answer:
0.68 : 0.32
Step-by-step explanation:
the probability of all the outcomes of an event is always 1 .
if P(E) = 0.32,
P(E') = 1 - 0.32
= 0.68
N.B that P(E') is the same as P( not E ).
since your answer should be given in the ratio form, as the odds against E ( probability not E : probability E),
P(E') : P(E)
0.68 : 0.32
