The probability of a baby being a boy is 0.514.
Nine baby births are selected and we have to find the probability that at last one of them is a girl.
P(At least one out of 9 is baby girl) = 1 - P(No baby girl)
= 1 - P(All 9 are baby boy)
= 1 - (0.514)^9
= 1 - 0.0025
= 0.9975
The probability that at least one out of 9 selected births is baby girl is 0.9975

Answer:
32km
Step-by-step explanation:
if you draw the diagram it looks like a right angled triangle then indicate the values and use the Pythagoras theorem to solve
To give you a boost multiply the hypotenuse by sin(θ) to get the length of the side opposite to the angle.
Break 48 into 40 and 8. 3(40) + 3(8). 3 times 40 is 120 and 3 times 8 is 24. So, 120+ 24= 144
