The probability that the first student is a girl is 5/10.
The probability of the second selection being a boy is 5/9.
(since the first selection was a girl, there are 9 students left)
The probability that the third student is a girl is 4/8
(there are 4 girls left after one was selected, and 8 students left in total, after the second selection.
The probability is (5/10)(5/9)(4/8)=0.139
Answer: 0.139
To calculate problems abound about compounding interest use the equation <span>A = P (1 + r/n)^<span>(nt), where A is the future price, P is the principal amount, r is the interest rate, n is the number of times the interest is compounded per year and t for the total years. To solve, A = 100 (1 + 0.08/1)^(1 x 15) = 317.22.</span></span>
The correct answer is -4^5-7/4
Bear with my working out lol,
8x3 = 24in^2
9x12 = 108in^2
6x7 = 42in^2
(11x4) / 2 = 22in^2
Total = 196in^2
Try that, I couldn’t tell where the tip on the triangle fell at. So it could be wrong but that is what I got and what I would put :)
