In a NiCd battery, a fully charged cell is composed of nickelic hydroxide. Nickel is an element that has multiple oxidation states. Assume the following proportions of the states:

X 0 2 3 4
p(X) p 0.23 0.35 0.20

(a) The missing probability p is equal to?

The missing probability p = 0.22.

Step-by-step explanation:

A fully charged cell is composed of nickelic hydroxide in a NiCd battery.

Nickel is known to be such an element that it has multiple oxidation states.

The proportions of the states are given as following.                                          

                   X                                   p(X)

                   0                                    p

                   2                                    0.23

                   3                                    0.35

                   4                                    0.2

The total probability of an event, which in this case, is the event that Nickel has oxidation states of either 0, 2 , 3 or 4, is always equal to 1.

Therefore we can write p + 0.23 + 0.35 + 0.2  = 1

Therefore  p = 1 - (0.23 + 0.35 + 0.2) = 1 - 0.78 = 0.22

The missing probability p = 0.22.

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
