Question

Find the probability for choosing a letter at random from the word: Probability P(not P) A.) 1/11 B.) 2/11 C.) 5/11 D.) 10/11​

Answer 1

D.) 10/11

Explanation:

Here the given word Probability has 11 letters in it. And we have to calculate the Probability of not selecting a letter P from the above word.

So the formula for calculating any probability is Total Favorable outcomes / Total number of outcomes.

Here total number of outcomes are 11 as word Probability has 11 letters.

So the probability of selecting letter P from word Probability =
`(1)/(11)`

Now the P(not P) = 1 - P(selecting letter P)

= 1 -
`(1)/(11)` =
`(10)/(11)`
