Answer: 5/36
Step-by-step explanation: We know that A U B means all the possible combinations that make event A or event B true. As we know, the only combinations that can make 4 is 1+3, 2+2, or 3+1, and the only combinations that can maker 11 is 5+6 and 6+5. This leaves us with a total of 5 combinations, and with a total of 36 combinations, that means that there is a 5/36 chance that the combinations of the dice add to either 4 or 11.

Answer:
(c)
Step-by-step explanation:
As given in the statement, we have:
Out of 4 games pieces, 1 is winner.
Probability to win =p=
Jeff has game pieces = n = sample size = 4
As we need to find the probability that he wins exactly 1 prize, we will use binomial probability here :
Evaluating at k=1, (k=1 as we need to find probability for exactly 1 prize won)
put n = 4, p =
P (X = 1) =
P =
Which is the probability that he wins exactly 1 prize and is option c.
Answer:
money you need to save per week ≥ price / number of weeks
Step-by-step explanation:
You have to determine the minimum amount of money you need to save each week. This amount of money multiplied by the number of weeks you spend saving must be greater or equal to the price of the item. That is:
number of weeks * money you need to save per week ≥ price
Isolating money saved:
money you need to save per week ≥ price / number of weeks
