you need to do 10-6 is 4 then 2x? is 4
The probability is 1/5 to get a red ball in 1st draw and a white ball in 2nd draw.
<u>Step-by-step explanation:</u>
- There are 1 red ball and 4 white balls in a box.
- The total number of balls in the box = 1 red + 4 white = 5 balls.
The two balls are drawn without replacement.
<u>Drawing the first ball :</u>
The first draw should be a red ball.
The probability to get a red ball = No.of red balls / Total balls in the box.
We know that, No. of red balls is 1 and total balls in the box is 5.
P(red ball) = 1/5
<u>Drawing the second ball :</u>
The second draw should be a white ball.
The probability to get white ball = No.of white balls / Total balls in the box.
We know that,
No. of white balls is 4.
The total balls in the box after the first draw will be 4 balls.
P(white ball) = 4/4
The probability of getting a red ball on the first drawn and a white ball on the second draw = P(red ball) × P(white ball)
⇒ (1/5) × (4/4)
⇒ 4/20
⇒ 1/5
Therefore, the probability is 1/5 to get a red ball in 1st draw and a white ball in 2nd draw.
Answer:
42.5 Units squared
Step-by-step explanation:
Rectangle: 9.0 * 3.5 = 31.5
Square: 2 * 2 = 4
Left Triangle: 2 * 2 * .5 = 2
Right triangle: 5 * 2 * .5 = 5
31.5 + 4 + 2 + 5 = 42.5
Largest to Smallest:-
First lets write all the numbers down. 45, 94, 85, 490, 85, 93, 85, 035, 85.
035 is 35.
So lets order them now.
The biggest number is 490 and smallest is 35 (035).
490 - 94 - 93 - 85 - 85 - 85 - 85 - 035 (35)
