X+2 =4
that would be a correct statement
121 is the smaller integer. Hope this helps! :)
Answer:
The probability that they will meet is 0.4375
Step-by-step explanation:
Let A and B be two friends who choose to meet the same one-hour period.Since there are 60 minutes in an hour therefore n= 60
A can wait for 15 minutes
So the probability of A to meet is given by P(A)= (15/60)= 1/4
Similarly
B can wait for 15 minutes
So the probability of B to meet is given by P(B)= (15/60)= 1/4
The probability that A cannot meet is given by 1- P(A)= 1-1/4= 3/4
Similarly
The probability that B cannot meet is given by 1- P(B)= 1-1/4= 3/4
And
The probability that both A and B cannot meet is given by = 3/4*3/4= 9/16
So the probability that both will meet = 1- 9/16= 7/16= 0.4375
Answer:
Step-by-step explanation:
A circle with radius r and centre (a, b) has an equation:
Solution :
Given :
P (never married) = P = 0.44
Sample size, n = 15
Let (n = 15, P = 0.44)
P(X = x) =
a). The probability that exactly two of them have been married is
P(X=2) =
= 0.0108
b). That at most two of them have never been married.
= 0.000167+0.001969+0.010828
= 0.012964
= 0.0130
c). That at least 13 of them have been married.
P(married) = 1 - P(never married)
= 1 - 0.44
= 0.56
= 0.012964
=0.0130
