The probability of drawing red on the first draw is 20/36. Having drawn red on the first draw, the probability of drawing red on the second draw is 19/35. The probability that both marbles are red is therefore;
Answer:
the answer is a
tell me if it’s rite or wrong I did the work as best as I could
let f(r)=sin^3r/cos^3r
so f(-r)= (sin(-r)/cos(-r))^3
=(-sinr/cosr)^3
=-f(r)
so it is odd function
Neck: In 2/3 of an hour Naomi will stretch her neck one (there's not enough time for two neck stretches, that would require an hour).
Legs: In 2/3 of an hour, she will stretch her legs twice (1 stretch every 1/3 of an hour for 2/3 of an hour equals 2).
Arms: In 2/3 of an hour she will stretch her arm four times (2/3 divided by 1/6 equals 4).
Total stretches: 1 neck stretch, 2 legs stretches, and 4 arms stretches.
