Answer:
Events E and F are independent.
Step-by-step explanation:
E = {multiple of 3} = {3, 6, 9, 12}
P(E) = 4/12
F = {even number} = {2, 4, 6, 8. 10, 12}
P(F) = 6/12
E and F = {even and multiple of 3} = {6, 12}
P(E∩F) = 2/12
In order for two events to be independent the following relationship must be true:
Testing this property:
The relationship holds true, thus events E and F are independent.
Answer:
50
Step-by-step explanation:
4,500÷90=50
and to check
90×50=4500
Answer: The expected waiting time is
Step-by-step explanation:
Since we have given that
Average waiting time for slow elevator = 3 min
Average waiting time for fast elevator = 1 min
probability that a person choose the fast elevator =
Probability that a person choose the slow elevator =
So, the expected waiting time would be
Hence, the expected waiting time is
2 sibblings is 34%
there are 50 sibblings total so
34 percent of 50=answer
'of' can be translated as multiply
34%=34/100=0.34
0.34 times 50=17
there were 17 perople weith 2 sibblings
