Help me out this is due. :}

Determine the required value of the missing probability to make the distribution a discrete probability distribution. x p(x) 3 0.23 4 ? 5 0.51 6 0.08 p(4) = nothing  (type an integer or a decimal.)

Marking brainliest rewrite the equation x = 65 - 60p by factoring the side that contains the variable p.

Ineed some on this. not sure how to solve.
