4/11

Practice makes perfect
When calculating probability, we are comparing the number of favorable outcomes to the number of possible outcomes. To calculate the probability that a randomly chosen letter tile is I, we will use the Probability Formula. P=Favorable Outcomes/Possible OutcomesIn the word MISSISSIPPI, there are 1 M, 4 I, 4 S, and 2 P letter tiles. The sum of these values is the number of possible outcomes. 1+4+4+2= 11 letter tiles Out of these, 4 are I letter tiles, which is the number of favorable outcomes. Now we have enough information to calculate P(I).
P=Favorable Outcomes/Possible Outcomes
P(I)=4/11
The probability of choosing a letter tile I is 411.
