Question

Five student $A,B,C,D$ and $E$ are competeing in a long distance race. Each students probability of winning the race is given below:

$A\to 20\%,B\to 22\%,C\to 7\%,D\to 15\%\text{and}E\to 36\%$.

(iv) Find the probability that either $A$ or $D$ will win the race​

Answer 1

Probability of $A$ or $D$ wins is the sum of their winnings probabilities

$=20\%+15\%$

$=35\%$

$=\frac{35}{100}$

$=0.35$

Henc, the probability that either $A$ or $D$ will win the race is $0.35$
