Answer:
128
Step-by-step explanation:
so i am sure you know that 1 hour is sixty minutes
so this is how it woulds
10/1 * 60/1 = 600 minutes
so that means that 10 hours would be equal to 600 minutes
then add on the 39 minutes
639
BUT WAIT there are the seconds
24/1 * 1/60 = 0.4
so 24 seconds is 0.4 (40%) of a minute
so it would take 639.4 minutes for saturn to make a full rotation
i hope this helped and please vote me for brainliest! have a nice day!
Answer:
Example:
A bag contains 3 black balls and 5 white balls. Paul picks a ball at random from the bag and replaces it back in the bag. He mixes the balls in the bag and then picks another ball at random from the bag.
a) Construct a probability tree of the problem.
b) Calculate the probability that Paul picks:
i) two black balls
ii) a black ball in his second draw
Solution:
tree diagram
a) Check that the probabilities in the last column add up to 1.
b) i) To find the probability of getting two black balls, first locate the B branch and then follow the second B branch. Since these are independent events we can multiply the probability of each branch.
ii) There are two outcomes where the second ball can be black.
Either (B, B) or (W, B)
From the probability tree diagram, we get:
P(second ball black)
= P(B, B) or P(W, B)
= P(B, B) + P(W, B)
