Answer:
x = - 80
Step-by-step explanation:
Given
- 6 = 
+ 4 ( subtract 4 from both sides )
- 10 = ( multiply both sides by 8 )
- 80 = x
Let p be the probability of success, p = 0.4.
Pr[2 success] = nC2 * p^2 * (1-p)^3 = 0.346
Pr[3 success] = nC3 * p^3 * (1-p)^2 = 0.230
Pr[4 success] = nC4 * p^4 * (1-p)^1 = 0.077
So, the probability of getting 2, 3, or 4 success, would be 0.356 + 0.230 + 0.077 = 0.663, alternatively, 66.3%.
