All the outcomes are 10 (possibilities)
To pull a quarter (total 3), its probability = 3/10 or 0.3
Now without putting the quarter back, the remaining total is now 9 (because one quarter was pulled out) so the probability of getting a penny is 2/9
But this is a conditional probability a) 1st pull a quarter & 2nd pull a penny
So the total probability is 3/10 x 2/9 =6/90 = 1/15 = 0.067
Answer:
a = 30 degrees; b = 60 degrees; and c = 105 degrees.
Step-by-step explanation:
Angle a and the 30 degree angle are vertical angles and thus are equal.
Since the interior angles of a triangle always add up to 180 degrees, 30 + b + 90 degrees = 180 degrees, so that b must be 60 degrees.
Angle c and the 75 degree angle are straight angles, and so their sum must be 180 degrees. Thus, c = 105 degrees.
