A sales analyst listed the probabilities of profits and losses in dollars for a certain company. Find the mean for the probabili

kakasveta [241]

Answer: The mean for the probability distribution will be 69.25.

Explanation:

Since we given that

$At\ x_1= -500 ,P(x) = 0.076\\$

$At\ x_2= -250,P(x)= 0.191\\$

$At\ x_3=0, P(x)= 0.265\\$

$At\ x_4=250 , P(x)= 0.316\\$

$At\ x_5=500 , P(x)= 0.152\\$

As we know the formula for expectation of x i.e. known as mean for the probability distribution,

$E(x)=x\sum_{1}^{5} P(x)$

So, we apply this formula in our case,

$-500\times 0.076+(-250)\times 0.191+0\times 0.265+250\times 0.316+500\times 0.512=69.25$

$\mu = 69.25$

Hence, the mean for the probability distribution will be 69.25.
