Question

On a particular day the number of vehicles passing through a crossing is as follows. Two wheelers = 57; Three wheelers = 33; Four wheelers = 30. A particular vehicle is chosen at random, what is the probability that it is not a four wheeler.

Answer 1

this might be ur answer

Answer 2

Given:

Number of two-wheelers = 57

Number of three-wheelers = 33

Number of four-wheelers = 40

To Find:

The probability that it is not a four-wheeler.

Solution:

Calculating total number of vehicles = Two wheeler + Three wheeler + Four wheeler

= 57 + 33 + 40

= 120

Number of vehicles which are not four wheelers -

=  57 + 33

= 90

Probability that it is not a four wheeler -

= 90/120

= 3/4

Answer: The probability that it is not a four-wheeler is 3/4
