Answer 1

3 heads=23

2 Heads=72

1Head=77

No Head=28

$\boxed{\mathbf{Probability=\frac{Favourable \:Outcomes}{Total\: Outcomes}}}$

(1)Getting 2 heads=72

Total Outcomes=200

$\boxed{\mathbf{Probability(2\:heads)=\frac{72}{200}}}$

$\boxed{\mathbf{Probability(2\:heads)=\frac{9}{25}}}$

(2)Getting At least 2 Heads.

In 3 heads We can Also Get 2 Heads

In 2 Heads We can also get at least 2 Heads.

Favourable Outcomes=72+23

=95

Total Outcomes=200

$\boxed{\mathbf{Probability(At\:least\:2\:heads)=\frac{95}{200}}}$

$\boxed{\mathbf{Probability(At\:least\:2\:heads)=\frac{19}{40}}}$
