A slot machine at a hotel is configured so that there is a 1/1200 probability of winning the jackpot on any individual trial. If a guest plays the slot machine 6 times, find the probability of exactly 2 jackpots. If a guest told the hotel manager that she had hit two jackpots in 6 plays of the slot machine, would the manager be surprised?

The probability is approximately one in a million (0.001% ).

It's a very little probability, so the manager would be really surprised.

Step-by-step explanation:

We have for this question to calculate with a binomial random variable, with n=6 and p=1/1200=0.00083 .

We have to calculate the probability of getting 2 hits in the sample of size 6.

The probability is approximately one in a million (0.001% ).

It's a very little probability, so the manager would be really surprised.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
