Answer:
Step-by-step explanation:
Can you label like which one is which please.
The probability of getting exactly 1 green will be 1/13.
<h3>What is probability?</h3>
The chances of an event occurring are defined by probability. Probability has several uses in games, in business to create probability-based forecasts,
Given data;
No of blue marbles= 5,
No of red marbles=6
No of green marbles=2
Total no of ball = 5+6+2
Total no of ball = 13
The probability of getting one green marble is;
P(G)=1/13
Hence, the probability of getting exactly 1 green will be 1/13.
