Answer:
a) The probability that Tommy takes a yellow counter is 0.20.
b) The probability that Tommy takes a blue counter is 0.
Explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
There are 5 red counters, 2 yellow counters and 3 green counters in a jar. Tommy takes a counter at random from the jar.
a) What is the probability that he takes a yellow counter?
b) What is the probability that he takes a blue counter?
The explanation of the answers are now given as follows:
a) What is the probability that he takes a yellow counter?
This can be calculated as follows:
Total number of counters in the jar = Number of red counter in the jar + Number of yellow counter in the jar + Number of green counter in the jar = 5 + 2 + 3 = 10
Probability of taking a yellow counter = Number of yellow counter in the jar / Total number of counters in the jar = 2 / 10 = 0.20
Therefore, the probability that Tommy takes a yellow counter is 0.20.
b) What is the probability that he takes a blue counter?
This can be calculated as follows:
Number of blue counter in the jar = 0
Probability of taking a blue counter = Number of blue counter in the jar / Total number of counters in the jar = 0 / 10 = 0
Since there no blue counter in the jar, the probability that Tommy takes a blue counter is therefore 0.
