Abowl contains 25 balls numbered 1 to 25. a ball is drawn and its number is noted. without replacing the first ball, another ball is drawn. the probability that the numbers on both balls are odd numbers is (text box)

13  balls are odd in 25

1st pick = 13/25 probability of picking an odd

2nd pick = 12/24 = 1/2 probability

13/25 x 1/2 = 13/50 probability

Answer would be 13/50

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
