Answer: 21°
Step-by-step explanation:
Since angles DAE and CBE are inscribed on arc AC, they r equal
Hence angle CBE = 42°
So angle DAE = 42/2 = 21°
Assuming that the probability of boys and girls is equal (in reality slightly more boys than girls are born), the probability is 1/2, simply because the older girl's gender is given and therefore not a part of the probability.
This question comes from the 'boy or girl paradox', a.k.a. the Mrs Smith Problem.
Answer:
Step-by-step explanation:
diameter = 4.275"
r = 4.275 ÷ 2 = 2.1375"
Area of circle = πr²
= 3.14 * 2.1375 * 2.1375
= 14.3463
≈ 14.3 in²
