###
Activity : Note the frequency of two-wheelers, three-wheelers and four-wheelers going past during a time interval, in front of your school gate. Find the probability

that any one vehicle out of the total vehicles you have observed is a two-wheeler.

Note: This is an activity, so we assume some values and solve

Let's assume these values

Type of Vehicles | Frequency |

Two wheelers | 150 |

Three wheelers | 25 |

Four wheelers | 75 |

We need to find Probability of getting a two-wheeler

Now,

Total number of vehicles = 150 + 25 + 75

= 150 + 100

= 250

Probability of getting two-wheeler = Number of two-wheelers/Total number

= 150/250

= 15/25

= 3/5

Thus, Required Probability is
**
3/5
