What can be used as a reason in a two-column proof? select each correct answer. a true premise a conjecture a definition a theorem

Answer :- A definition and a theorem can be used as a reason in a two-column proof.

Explanation:-

A two column proof is assembled into statement and reason columns, where each statement should have verified reason. The reason in a two column proof are usually given information, vocabulary definitions, postulates and previously proved theorems.

Therefore, from the given options a definition and a theorem can be used as a reason in a two-column proof.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
