A) 1 to 5
B) 1 to 4
C) 5 to 1
D) 4 to 1

Accepted Answer

The odds in favor of an event are calculated as the ratio of the probability of the event occurring to the probability of it not occurring. The probability of getting a hit is 0.200, and the probability of not getting a hit is 0.800. The odds in favor are 0.200:0.800, which simplifies to 1:4.

A) 5 to 4
B) 1 to 4
C) 4 to 1
D) 4 to 5

Question 8

Solve the problem.
-Seven slips of paper marked with the numbers 1, 2, 3, 4, 5, 6, and 7 are placed in a box and mixed well. Two are drawn. What are the odds that the sum of the numbers on the two selected slips is not 6?
A) 9 to 1
B) 21 to 2
C) 19 to 1
D) 19 to 2

Accepted Answer

The total number of ways to draw 2 slips out of 7 is 7C2 = (7*6)/(2*1) = 21. The combinations that sum to 6 are (1,5), (2,4), and (5,1), (4,2), which are 2 distinct pairs since order doesn't matter in this context. So, there are 21 - 2 = 19 combinations that do not sum to 6. The odds in favor are 19 successful outcomes to 2 not successful, or 19 to 2.

-Seven slips of paper marked with the numbers 1, 2, 3, 4, 5, 6, and 7 are placed in a box and mixed well. Two are drawn. What are the odds that the sum of the numbers on the two selected slips is 7?
A) 1 to 7
B) 2 to 21
C) 1 to 6
D) 1 to 9

Accepted Answer

There are 21 possible pairs of slips (since 7 choose 2 is 21). The pairs that sum to 7 are (1,6), (2,5), and (3,4), which are 3 pairs. The odds are calculated as the number of successful outcomes to unsuccessful ones, which is 3 to 18, simplifying to 1 to 6.
