Acoin is tossed and a standard number cube is rolled. what is the probability that the coin shows head and the number cube shows an even number?
a: 1/6
b: 1
c: 1/4
d: 1/2

The total possibility that the head and even no on dice appears is 3. and total possible choice are 12 {head ---> (1,2,3,4,5,6) & tail ---> (1,2,3,4,5,6)}. so the probability is 3/12= 1/4.

C: 1/4

answer:

c. the third graph

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
