Two cards are drawn one at a time from a full deck of cards. a) what’s the probability they are an ace or a heart? b) what’s the probability they are neither ace nor a heart?

Probability of ace drawn is: 4/52

Probability of heart drawn is: 13/52

For question (a)

P(ace or heart)=p(ace) + p(heart)

P(ace or heart)=4/52 + 13/52

P(ace or heart)=17/52

For question (b)

P(ace)' =1 - 4/52 = 48/52

P(heart) =1 - 13/52 = 39/52

P(neither ace nor heart) = 48/52 × 39/52

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
