Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Suppose on your first try you get a bag that contains sand, so you throw it away. Which phrase tells your chances of choosing the bag of candy on your second try?

A	1 chance in 1
B	1 chance in 2
C	1 chance in 3

Explanation:

Detailed explanation-1: -Expert-Verified Answer n(S) is the number of elements in the sample space. n(S) = 1 + 1 = 2. The probability of choosing 3 or 4 will be2/2 = 1.

Detailed explanation-2: -Probability determines the likelihood of an event occurring: P(A) = f / N. Odds and probability are related but odds depend on the probability. You first need probability before determining the odds of an event occurring.

Detailed explanation-3: -A probability of 1 means that the event will happen. If the probability of a road traffic accident was 1 there would be nothing you could do to stop it. It will happen. In practice probabilities associated with everyday life events lie somewhere between 0 and 1.

Detailed explanation-4: -The formula for finding the either/or probability for overlapping events is P(A) +P(B)-P (A and B). This formula is similar to the non-overlapping events, but we must subtract the probability that the outcomes may happen together. P (A or B) = P(A) + P(B)-P (A and B)
