Answer:
- Set A = { 5, 25, 15, 35 }
- the set of multiples of 5
Step-by-step explanation:
Words to describe the set:
A set can also be described by just defining it using plain words. For example, the set A= {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday} can be described using words like “the set of days of the week”. Another example can be “the set of months of the year”.
Let X be the number of boys in n selected births. Let p be the probability of getting baby boy on selected birth.
Here n=10. Also the male and female births are equally likely it means chance of baby boy or girl is 1/2
P(Boy) = P(girl) =0.5
p =0.5
From given information we have n =10 fixed number of trials, p is probability of success which is constant for each trial . And each trial is independent of each other.
So X follows Binomial distribution with n=10 and p=0.5
The probability function of Binomial distribution for k number of success, x=k is given as
P(X=k) = 
We have to find probability of getting 8 boys in n=10 births
P(X=8) = 
= 45 * 0.0039 * 0.25
P(X = 8) = 0.0438
The probability of getting exactly 8 boys in selected 10 births is 0.044
Answer:
$21 the minimum Bob has to may will be the amount payed regardless of the number of passengers in the taxi
$256/4 hrs = 64 hrs
3 hrs x $64 = $192
2 hrs x $64 = $128
$256 + $192 + $128 = $576
Or
(4+3+2) x $64 = $576
9 x $64 = $576
