Answer:
z=2.27
Step-by-step explanation:
where z is the deviation from mean.
mean (μ) = 35 inches
standard deviation (σ) = 11 inches
last year snow fall (x) = 60 inches
z=2.27
now, the standard deviation for the 60 inches snow from the mean is calculated to be 2.27
The value of is -80

Evidently the quesiton is incomplete.
It is logic that the actions are roll a die and draw a card.
The two events are indepent, so the combined probability is the sum of the individual probabiliites.
Probability = number of positive events / number of possible events
Probability of rolling an even number = number of faces with even numbers / total number of numbers.
Probability of rolling an even number = 3 / 6 = 1/2
Probability of drawing an ace = number of aces in the deck of cards / number of cards
Probability of drawing an ace = 4 / 52 = 1 / 13
Combined probability = 1/2 + 1/13 = (13 + 2) / 26 = 15 / 26
Answer: option D. 15 / 26
