Ruby flipped the coin and spun the spinner below. What is the probability that the coin will land on heads AND the spinner will land on either a 2 or a 3?
A. 1/2
B 1/4
C. 1/10
D. 1/3

B.  1/4.

Step-by-step explanation:

There are 2 2's and 3 3's on the spinner and a total of 10 sectors, so the probability of getting a 2 or 3 = 5/10 = 1/2.

The probability of a head is 1/2.

So the required probability = 1/2 * 1/2 = 1/4.

first question answer is 3x^3+6x^2-24x+27

Second question answer=a^2-ab
