Probability of red marbles = 8/25
Step-by-step explanation:
Complete question
A jar contains 8 red marbles numbered 1 to 8 and 12 blue marbles numbered 1 to 12. It alse has 5 white marbles numbered 100, 200, 300, 400, and 500. A marble is drawn at random from the jar. Find the probability of the given event.
a) The marble is red
Total number of marbles = 8+12+5 = 25
Probability of red marbles = total number of red marbles/Total marbles
Probability of red marbles = 8/25
Answer:
Step-by-step explanation:
Y/1 = 2x + 5
Y = 2x + 5
Y = 2x + 5
When x = 1
Y = 2 ×1 +5
Y = 2 + 5
Y = 7
When x =0
Y = 2 × 0 + 5
Y = 5
When x = -2
X = 2 × -2 + 5
X = 1
( Make a table in the side of the page)
X | 1 0 -2
_ _______
Y 7 5 1
Answer:
1/3 more
Step-by-step explanation:
2/3 - 1/3 = 1/3
Mean = np = 60(0.7) = 42
Standard deviation = sqrt(npq) = sqrt(60(0.7)(0.3)) = 3.55
