Answer: 2/11
Step-by-step explanation:
We are going to solve this by using a tree diagram. It makes it a lot easier. The tree diagram is attached below.
From the tree tree diagram,
Probability of picking a blue ball at the first draw is 5/11
Prbability of picking ble at the second draw, if the balls are picked without replacement is 4/10
Probability of drawing two blue balls are;
P(B,B) = 5/11 × 4/10 = 20/ 110
Divide the numerator and denominator by 10
P(B,B) = 2/11
Answer:
27
Step-by-step explanation:
3 x 9 = 27
you just multiply the two. (if it asks for temperature after the hours just subtract)
