1. Your city has 700 000 households, and the probability that a household has exactly one vehicle is 17/23.
a) Determine the number of households that can be expected to have exactly one vehicle.
17/23 * 700,000 = ?
To determine the number of households that can be expected to have exactly one vehicle, you will need to calculate the expected value.
The expected value is calculated by multiplying the probability of an event occurring by the number of possible outcomes for that event.
In this case, the probability of a household having exactly one vehicle is given as 17/23.
To find the expected number of households with one vehicle, you can multiply the probability by the total number of households in the city.
Expected number of households with one vehicle = (17/23) * 700,000
= 510,869.57
Rounded to the nearest whole number, you can expect approximately 510,870 households in the city to have exactly one vehicle.
