In any situation that has only two possible outcomes, each outcome will have probability 1/2 . True or false? Why
Solution:
We know that
Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
Probability of each outcome will be 1/2 only if two outcomes are equally likely otherwise not.
Therefore, the statement is false.
✦ Try This: A boy calculates that the probability of her winning the first prize in a lottery is 0.04. If 2000 tickets are sold, how many tickets has she bought?
Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
Consider x as the number of tickets bought by the girl
From the question we can write it as
x/6000 = 0.08
x = 0.8 × 6000
x = 480
Therefore, she bought 480 tickets.
