What is the probability of drawing yellow marble followed by a red marble from a bag containing 12 yellow marbles, 16 red marbles, and 15 green marbles if the first marble is not replaced?

12 +16 +15 = 43 total marbles

12 are yellow so first pick you have 12/43 probability of picking yellow

 without replacement there would be 42 marbles left

 there are 16 red ones so you  have a 16/42, reduces to 8/21 probability of picking red

 probability of picking yellow then red =

12/43 x 8/21 = 96/903, reduces to 32/301 probability

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

the anwser is d) 75°
