Player A has entered a golf tournament but it is not certain whether player B will enter. Player A has probability 1/6 of winning the tournament given player B enters and probability 1/4 of winning given player B does not enter the tournament. The probability that player B enters the tournament is 1/3. Find the probability that player A wins the tournament.

i'm sorry i don't know

step-by-step explanation:

might be the correct answer will be question number 2

just go here

its what i use

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
