At a fair, $70$ boys, $80$ girls, $20$ men, and $30$ women have come. Find the probability that a person selected at random to be a prize winner is a woman.

$80$ bulbs are selected at random from a lot and their lifetime (in $hrs$) is recorded in the form of a frequency table given below:

Lifetime (in hours)	$300$	$500$	$700$	$900$	$1100$
Frequency	$10$	$12$	$23$	$25$	$10$

The probability that a bulb selected randomly from the lot has a lifetime less than $900$ hours is:

The maximum value of the probability of any event is ...........

$A$ recent survey found that the ages of workers in a factory is distributed as follows:

Age (in years)	$20-29$	$30-39$	$40-49$	$50-59$	$60$ and above
Number of workers	$38$	$27$	$86$	$46$	$3$

If a person is selected at random,find the probability that the person is $40$ years or more.

The probability that a non-leap year should have $53$ Sundays is ............ (in $/7$)

Following is the information about vehicles passing in front of a city temple in one hour:

Vehicle type	Two-wheelers	Three-wheelers	Four-wheelers
