<u>Given</u><u> </u><u>:</u>
- White balls = 5
- Red balls = 8
- Yellow balls = 7
- Green balls = 4
<u>Answer</u><u> </u><u>1</u><u> </u><u>:</u><u>-</u>
We know that,
- P (E) = No. of favourable outcomes / Total number of outcomes.
>> Total no. of outcomes = 5 + 8 + 7 + 4
>> Total no. of outcomes = 24
As there are 4 green balls. Therefore,
- P (E) = 4 / 24
- P (E) = 2 / 12
- P (E) = 1 / 6
<u>Answer</u><u> </u><u>2</u><u> </u><u>:</u><u>-</u>
We know that,
- P (E) = No. of favourable outcomes / Total number of outcomes.
>> Total no. of outcomes = 5 + 8 + 7 + 4
>> Total no. of outcomes = 24
As there are 8 red balls. Therefore,
- P (E) = 8 / 24
- P (E) = 4 / 12
- P (E) = 2 / 6
- P (E) = 1 / 3
<u>Answer</u><u> </u><u>3</u><u> </u><u>:</u><u>-</u>
We know that,
- P (E) = No. of favourable outcomes / Total number of outcomes.
>> Total no. of outcomes = 5 + 8 + 7 + 4
>> Total no. of outcomes = 24
As there are 15 balls that are neither green nor white. (Red balls+ yellow balls)
- P (E) = 15 / 24
- P (E) = 5 / 8
1 1/4 * 4
= 5/4 * 4
= 20/4
= 5

Answer:
x = -3
Step-by-step explanation:
to solve this equation you should first find the LCD or least common denominator for 2 and 6
the LCD is 6
so you should multiply each side by six
3x + 15 - x - 3 = 6
now combine like terms
2x + 12 = 6
now subtract both sides by 12
2x = -6
lastly divide everything by 2
x = -3
that is your answer
Answer:
by simplifying both sides of the inequality, then isolating the variable.
