....................................

When two coins are tossed then all possible outcomes are HH , HT , TH and TT.

Total number of outcomes = 4

•°• P(getting one head) = 3/4

Answer 2

Concept:

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.

Given:

Two coins are tossed

Find:

the probability that only one head is obtained.

Solution:

When two coins are tossed then all possible outcomes are HH , HT , TH and TT.

Total number of outcomes = 4

•°• P(getting one head) = 2/4

Therefore, the probability that only one head is 2/4
