A pair of coins is tossed. What is the probability of two tails?

A. 1/2
B. 1/4
C. 1

Respuesta :

B 1/2 x 1/2 = 1/4 (every flip of a coin has 1/2 chance of landing on either side, so you multiply the chances by each time you flip it, for example if you flip it again you would multiply it by 1/2 again)

The correct answer is B. 1/4

What is probability?

  • Probability refers to the chance of occurring of an event.
  • Probability is always ≤ 1

How to calculate  probability ?

Probability can be found by dividing the favourable cases by the total possible cases.

How to calculate probability of two tails?

  • If a coin is tossed, there are two possible results. They are either  a head or a tail.

So, the probability of getting a tail from a coin after being tossed is 1/2

  • According to the question, two coins are tossed.

The possible outcomes are,

  • Head in both the coins
  • Tails in both the coins
  • Head in first coin and tail in second coin
  • Head in second coin and tail in second coin

There are total 4 outcomes out of which only the case of both tails is favourable.

So, the probability is 1/4.
