The probability of the spinning arrow stopping in the shaded region (Fig. 3.4) is 1/2. State whether the statement is true or false.

Solution:

Given, The probability of the spinning arrow stopping in the shaded region (Fig. 3.4) is 1/2.

We have to determine if the given statement is true or false.

Total parts of the spinning arrow = 4

Number of shaded region = 2

The probability of an event = Number of outcomes favourable to the event/Total number of outcomes in the experiment

Probability of the spinning arrow stopping in the shaded region = 2/4

= 1/2

Therefore, the required probability is 1/2.

✦ Try This: A coin is tossed 15 times and the outcomes are recorded as follows : H T T H T H H H T T H T H T T. The chance of occurence of a tail is 50 per cent. State whether the statement is true or false.
