(b) 0.5732
(d) None of these.
(a) 0.374
(c) 0.0684​

Answer 1

Answer:

0.0684

Step-by-step explanation:

Since people born on February 29 th would celebrate their birthday only once in 4 years ( leap year)

Therefore total number of days =( 365 × 4) + 1 = 1461

Therefore the percentage is ( 29th February)

1461×100=0.0684

Ex - One child is born on one day is = x

In the three years total child is = 365 × x × 3 = 1095+ 366x = 1461x percentage of children who were born on in the 29 February = favorable / sample

100x/1461=.06844
