The answer will be 14/20 because there a total of 20 beads and 8 red beads and 6 green beads which is 14 out of 20 total beads

Given that there are 8 red beads, 6 yellow beads, and 6 green beads in the containder.

So total number of beads = 8+6+6=20

They want to pick only green or red bead so favorable number of beads = 8+6= 14

probability of any event is given by formula

Probability= [favorable number of outcomes]/[Total number of outcomes]

So the probability of getting green or red bead in first draw = 14/20

After each draw the drawn bead is replaced means put back into container.

In that case number of beads will be same as it was in the beginning.

So the probability of getting green or red bead in second draw = 14/20

This process repeats 60 times so the required probability

=\frac{14}{20}*\frac{14}{20}*\frac{14}{20}*...*\frac{14}{20} (60 times repeatition)

=(\frac{14}{20})^{60}

So the final answer is (\frac{14}{20})^{60} .

What is the P(H,H,H,T,T) on 5 flips of a coin?<br><br> I need help
meriva

Answer:

The probability for Heads will be 60% or 3/5.

The probability for Tails will be 40% or 2/5.

Step-by-step explanation:

The coin flipped 5 times and landed on Heads 3 times. This shows that out of 5 situations, 3 situations were Heads. Therefore, the  probability is 3/5.

The coin landed on Tails 2/5 times the coin was flipped, which is basically the probability.
