Question

In a simultaneously toss of two coins, what is the probability of exact one head ?​

Answer 1

Sample space(TT,TH,HT,HH)

2/4

1/2

Answer 2

Step-by-step explanation:

ANSWER:-

In simultaneous toss of two coins:-

The sample space required is:-

HH

HT

TT

TH

• Where H refers to Head
• Where T refers to tales

So we need to find out where we find exactly one head.

We can see that:-

1. In second case
2. In fourth case

We can see only one head

Total outcomes = 4

Single head = 2

P( one head exact ) = 2/4

P(E) = 1/2 is the answer.

More:-

Sample Space :-

This is the term which is used to define all the possible cases in the given case to find the applicable probability.

Note:-

P(E) = Favourable outcome / Total outcomes
