Probability of having at least 1 boy = 1 - the probability of having ALL girls.

P(5 girls) = (1/2)⁵ = 1/32

P(At least 1 boy) = 1 - 1/32 = 31/32

Answer: 31/32

Without subtracting 8.5 - 4.64, determine what digit will be in the hundredths place. Explain

murzikaleks [220]

8.5 is the same as 8.50, right? So just take the digit in the hundredth place of both decimals and subtract. You'd be doing 0-4 so you can go ahead and borrow a number to make 10-4, which equals 6. So without subtracting 8.5 and 4.64, you can determine that 6 will be in the hundredth place. Hope this helps!
