Hi
P(C) is first B then C
so P ( B) = 0.4
event C is 0.2 also P( C) = 0.4 x 0.2 = 0.08
X would equal 0 because u would use the distribution 3x+3=3x+3 and then subtract three from the three on the other side and then subtract 3x from 3x and then 0
Step-by-step explanation:
Let x be the lost number then
x - 2/3 = 1/2
x = 1/2 + 2/3
x = (3 + 4)/6
x = 7/6
