Answer
View full question & answer→Number of times 2 tails come up $=83$
Total number of times the coins were tossed $=300$
$
\begin{aligned}
& P(2 \text { tails will come up })=\frac{\text { Number of times } 2 \text { tails come up }}{\text { Total number of times the coins were tossed }} \\
& =\frac{83}{300}
\end{aligned}
$
Number of times 1 tail come up $=140$
Total number of times the coins were tossed $=300$
$
\mathrm{P}(1 \text { tail will come up })=\frac{\text { Number of times } 1 \text { tail come up }}{\text { Total number of times the coins were tossed }}
$
$
=\frac{140}{300}=\frac{7}{15}
$
Number of times no tail come up $=77$
Total number of times the coins were tossed $=300$
$
P(\text { no tail will come up })=\frac{\text { Number of times no tail come up }}{\text { Total number of times the coins were tossed }}
$
$
=\frac{77}{300}
