Answer :
The probability that both boys will pick blue pens will be 1/6.
What is the definition of probability?
The possibility of an event is expressed by probability. This field of mathematics is concerned with the occurrence of a random event. The value varies from 0 to 1. In mathematics, probability is used to forecast the likelihood of occurrences occurring.
The potential of something happening is referred to as probability. The probability distribution makes use of this fundamental principle in probability theory. Before we can evaluate the likelihood of an event occurring, we must first know the total number of alternatives.
P(E) is the chance that an event will occur divided by the total number of outcomes.
Now,
Given that blue pens=4 and red pens= 5.
Total pen=9
then probability of Tom picking a blue pen=4/9
now blue pen left=3 and total pen left=8
so probability of Corey picking a blue pen=3/8
Therefore, Probability of both picking a blue pen=4/9*3/8
=12/72
=1/6
Hence,
The probability that both boys will pick blue pens will be 1/6.
