1) Rolling a die Sample Space = {1,2,3,4,5,6} Total number of outcomes in sample space = 6 Favorable outcomes = Odd number Number of Favorable outcomes = 3
Probability of getting an odd number = 3/6
2) Tossing a coin Sample Space = {H, T} Probability of getting a head= 1/2
The probability of getting odd number and head will be the product of two probabilities, which will be = 3/6 x 1/2 = 3/12
Thus there is 3/12 = 1/4 (0.25 or 25%) probability of getting an odd number and a head in given scenario.
The problem is asking us to find how many days food would last. Since the food shelter uses 1 3/5 each day, the 12 bags of food would be split into 1 3/5 they use each day.
