The letters that form the word mississippi are placed in a bowl. what is the probability of choosing two letters, one after the other, and choosing a p and then an i? question 9 options: 4/55 6/11 8/121 3/55

Option C (8/121).

Step-by-step explanation:

The word MISSISSIPPI contains 11 letters: 1 M, 4 I, 4 S, and 2 P. Thus the probability of choosing one letter can easily be determined.

P(Letter M is selected) = number of M / number of letters = 1/11.

P(Letter I is selected) = number of I / number of letters = 4/11.

P(Letter S is selected) = number of S / number of letters = 4/11.

P(Letter P is selected) = number of P / number of letters = 2/11.

Therefore, the probability of selecting P in the first attempt is 2/11. If the replacement is allowed, then the probabilities will remain unchanged for all the letters. So the probability of selecting I in the first attempt is 4/11. Assuming that the selection of the letters is independent, we can safely multiply both the probabilities. Therefore, 2/11 * 4/11 = 8/121.

So the correct answer is C!!!

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
