A game consists of spinning an arrow which comes to rest pointing at one of the regions (1, 2 or 3) (Fig. 13.1). Are the outcomes 1, 2 and 3 equally likely to occur? Give reasons
Solution:
Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that
Probability = Favourable outcomes/ Total outcomes
From the question,
Total outcome = 360
Here
P (1) = 90/360 = 1/4
P (2) = 90/360 = 1/4
P (3) = 180/360 = 1/2
Therefore, it is clear that the outcomes are not equally likely to occur.
✦ Try This: If A and B are two independent events, the probability that both A and B occur is 5/8 and the probability that neither of them occurs is 7/8, The probability of the occurrence of A is
