Given:
The table and the relative frequency histogram show the distribution of the number of tails and three coins are tossed.
To find:
The probability
.
Solution:
In the given table T represents the number of tails.
From the given table it is clear that the value of probability is
and
. So,

Therefore, the probability
is equal to
.
.22a is the algebraic expression. I hope this helps and have a great day!
