Question

In the simulteneous tossing of two fair coins, the probability of having at least one head is:
A) 0.75
B) 0.25C) 1
D) 0.5

Answer 1

Head=H

Tail=T

If 2 Coins Tossed Together.Outcomes are-

HH

TH

HT

TT

Total Outcomes=4

At Least 1 head Outcomes Are

HH

TH

HT

1 Head Outcomes=3

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

Favourable Outcomes=3

Total Outcomes=4

$\boxed{\mathbf{Probability(1H)={3}{4}}}$

In Simplest Form

$\frac{3}{4} = 0.75$

$\boxed{\mathbf{Probability(1H)=0.75}}$
