A box contains 100 balls, numbered from 1 to 100. If three balls are selected at random and with replacement from the box, what
butalik [34]

Answer:

1/2.

Step-by-step explanation:

Let O = an odd number and E an even number.

The possible outcomes for  an odd sum are:

OOO

OEE

EOE

EEO

The probability of an odd on each pick = 50/100 = 1/2 and for an even it is also 1/2.

Prob( O O O) = 1/2*1/2*1/2 = 1/8.

The probability for the other 3 possible outcomes is also 1/8 , therefore the probability  for odd number totals = 4 * 1/8

= 1/2.

Consider the equation below -2(5x + 8) = 14 + 6x complete the statements below with the process used to achieve steps 1-4
Ad libitum [116K]

Step-by-step explanation:

1. Distribute the -2. multiply-2 with 5x and 8. it will be -10x-16=14+6x. For me, i make small numbers negative or positive than big ones. Add 16 to both sides. it will be -10x=30+6x. Subtract 6x. -10x-6x=-16x. Divide both sides by 16. x=30/16= 1 and 14/16
