Before the trials, you are equally as likely to get the black ball in the 1st trial(0 white balls drawn) to the 5th trial(4 white balls drawn). So this is an uniform distribution with
Thus, the pmf is:
The answer is cubic trinomial because the highest exponent is 3 which makes it a cubic function and there are 3 terms which makes it a trinomial
Answer:
The withdrawal of $25 involved more money.
Step-by-step explanation:
We have been given that one customer made a $25 withdrawal from a savings account. The other customer made a $15 deposit.
