Please help me, I need help I don’t know what to do.

1/4

Step-by-step explanation:

There are two possible outcomes when we flip a coin, heads or tails

P(heads) =1/2

Then we flip again

P(heads) =1/2

P (heads, heads) = P(heads) * P(heads) since they are independent events

                            =1/2(1/2 )= 1/4

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
