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
