Answer: $6,400

Step-by-step explanation:

First, let's take the given numbers

Starts the account with $1600

Deposits $200 each week after opening it

25 weeks

We can't count the first week because it says "thereafter"

So we need to do 24x200

which is 4,800

Now we must add the original amount deposited and the amount of money added in 25 weeks

1,600+4,800

$6,400

For a group of 100 people, compute(a) the expected number of days of the year that are birthdays of exactly 3 people.(b) the exp

Scilla [17]

Answer:

Step-by-step explanation:

Leaving leap years, a year contains 365 days.

For a group of 100 people, each person is independent of the other and probability of any day being his birthday has a chance of

$\frac{1}{365}$

a) Probability that exactly 3 people have same birthday = $\frac{1}{365^3}$

Each day is independent of the other

And hence no of days having exactly 3 persons birthday out of 100 persons is binomial with n = 365 and p = $\frac{1}{365^3}$

Expected value of days = np = $\frac{1}{365^2}$

b) Distinct birthdays is binomail with p =1/365 and n = 365

Hence

expected value = np =1

Tyrell says if you subtract 1 from a number you get an even number.he writes these two equations as examples. 3-1=2 11-1=10

Anna11 [10]

Answer:

No Tyrell is incorrect.

Step-by-step explanation:

Tyrell is incorrect because if you take any even number and subtract one from it you would get an odd number. For example take 20, if you do 20-1 then that would give you 19.
