Answer:
1/38 of Kelly's beads are blue.
Step-by-step explanation:
four eighths = 1/2 or 1 half
1/2 of them are red.
18 white beads, so number of red beads have to be bigger than 18 since she has blue beads too.
So, we can just estimate she has just one blue bead so then the 18 whites become 19 so we need to make red beads the same amount as it is half of the total.
The total is 38 since 19 + 19 = 38 (total beads)
So, blue is 1/38 as a fraction.
Hope this helps. :)

Answer:
<u>If A and B are independent events, P(A and B) = P (A) * P (B)</u>
Step-by-step explanation:
Let's recall that independent events means that when one event occurs, it has no impact or influence on the probability of another event occurring. Here’s an example. Let’s say that we have two events, A and B.
Event A : it rains in Seattle
Event B : the Super Bowl match is cancelled in Miami
The two events are independent; if it rains in Seattle, this will have no impact on the probability that the Super Bowl match is cancelled in Miami. Raining in Seattle and the cancellation of the Super Bowl are independent events, therefore:
<u>P(A and B) = P (A) * P (B)</u>
