On tossing two coins simultaneously,find the probability of getting no tail.

The probability that a leap year,selected at random,will contain $53$ Sundays is .........

$A$ fair coin is tossed $200$ times and the tail occurs $92$ times,then find the probability of getting a head.

$A$ die is thrown $400$ times with the frequencies for the outcomes $1, 2, 3, 4, 5$ and $6$ as given in the following table:

Outcome	$1$	$2$	$3$	$4$	$5$	$6$
Frequency	$68$	$70$	$74$	$54$	$70$	$64$

Find the probability of getting each outcome.

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

Vehicle type	Two-wheelers	Three-wheelers	Four-wheelers
Frequency	$90$	$35$	$25$

Find the probability that the vehicle passing through the temple is a two-wheeler.
