A study by the department of education of a certain state was trying to determine the mean SAT scores of the graduating high school seniors. The study examined the
scores of a random sample of 90 graduating seniors and found the mean score to be
515 with a standard deviation of 103. At the 95% confidence level, find the margin of
error for the mean, rounding to the nearest tenth. (Do not write +).

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
