Amarble is drawn from a random bag that contains 3green 4yellow 5 blue and 8pink marbles what’s the probability that the marble drawn will be green or blue?

It would be 8/20 since there is a total of 20 marbles all together and the wanted marbles together will be 8. In percentage would be 40%^

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
