This will not help determine the distribution nor the lowest or highest score. We cannot determine which popul...

Probability that it rains all 5 days = 1/2 * 1/2 * 1/2* 1/2 * 1/2

we need to find probability of raining exactly 3 days - in no particular order... which is 5 C 3 = 5*4*3/3*2*1 = 10

Probability of raining 3 days exact in 5 day period = 10 * 1/2^5 = 5/16

Q3.

All possible events - 5: (2,6 3, 5 4, 4 5, 3 6, 2)

Desired events - 2: (3, 5 5, 3)

Probability = desired events/possible events = 2/5

answer is D: 2/5

Q1: Backsolve.

Start with C. (3^(x-1)) = 3^3x/3^3= 10

which is 3^3x = 90x3

Square both sides

(3^3x)^2 = 8100 x 9
which is 3^6x = 8100x9

Which is more than 8100. Hence the answer should be lower than 10.

Pick D - 10/3. If you solve you will get 3^6x = 8100. Hence answer is D
