Question

A coin is tossed. Which of the following is the probability of getting head?
A. 0
B.
$\frac{1}{2}$
C. 1
D. none of these ​

Answer 1

Correct option is

B

2

1

Tossing of a coin at random can give only two results, i.e. Heads or Tails.

⇒ Total number of outcomes possible =2

Probability =

Total Outcomes

Favourable Outcomes

=

2

1

Answer 2

The probability of the event = 0.5

Explanation:

Given:

1. A coin is tossed.

To find:

The probability of getting head

PROBABILITY:

Probability = Number of outcomes(A)  / total number of outcomes(S)

P(A) = n(A)/ n(S)

The probability of the event lies between 0 and 1

==> The answer must between 0 and 1

Tossing a coin

Sample space = n(S) = Total number of outcomes

The outcome of coin is Head and a Tail

n(s) = 2

The probability of getting head

n(A) = Number of outcomes

==> There is 2 chances head and tail

==> The outcome is head

so, n(A) = 1

P(A) = n(A)/n(S)

p(A) = 1/2

P(A) = 0.5

The probability of the event lies between 0 and 1

The probability of the event = 0.5
