Question

Ram and Shyam are playing a match. If the probability of Ram winning the match is 0.6, then find the probability of Shyam winning the match.

• A. 0.2
• B. 1
• C. 0.8
• D. 0.4

Answer 1

The correct option is D 0.4

Given: Probability of Ram winning the match P(R) = 0.6.
Let, the probability of Ram winning the match be P(R)
Probability of Shyam winning the match be P(S).

If Ram is winning the match, then Shyam is not winning the match. Thus, these two are complementary events.
We know that the sum of the probabilities of complemenatry events is 1.
$\Rightarrow P\left(R\right)+P\left(S\right)=10.6+P\left(S\right)=1P\left(S\right)=1-0.6P\left(S\right)=0.4$
