Answer

Explanation:

Step1: Identify relevant probabilities

The probability of getting an 'I' is $P(I)=0.22$ and the probability of getting a 'G' is $P(G)=0.26$.

Step2: Use addition rule for mutually - exclusive events

Since getting an 'I' and getting a 'G' are mutually - exclusive events, the probability of getting an 'I' or a 'G' is $P(I\cup G)=P(I)+P(G)$. $P(I\cup G)=0.22 + 0.26$

Answer:

$0.48$
