What’s the answer
mine says P(not blue)=? so how do i do it.
don't get it
WHAT IS IT
To find the experimental probability of P(not blue), you need to add up the number of times the spinner landed on any color that is not blue. From the table, you can see that the spinner landed on red 20 times, green 9 times, and yellow 11 times. So the total number of times the spinner did not land on blue is:
20 + 9 + 11 = 40
Since the spinner was spun 50 times, the experimental probability of P(not blue) is:
40/50 = 0.8
So the answer to P(not blue) is 0.8.
To find the experimental probability of an event, you need to divide the number of times the event occurred by the total number of trials.
1. For the first question about the spinner, let's calculate the experimental probability of not getting red. The table shows that red occurred 20 times out of 50 spins. So, to find the probability of not getting red, we subtract the number of red spins from the total number of spins: 50 - 20 = 30. Therefore, the experimental probability of not getting red is 30/50 = 0.6.
So, the answer is (a) 0.6.
2. Moving on to the second question about flipping two coins, let's compare the experimental and theoretical probabilities of getting at least one tails. To find the theoretical probability, we need to count the total number of possible outcomes and the number of favorable outcomes.
In this case, we have 2 coins, and each coin has 2 possible outcomes (heads or tails). Therefore, the total number of possible outcomes is 2*2 = 4.
The favorable outcomes, in this case, are when at least one coin lands tails up. From the table, we can see that there are 34 outcomes where at least one tails shows up.
So, the theoretical probability of getting at least one tails is 34/4 = 0.85.
Now, let's compare it to the experimental probability. From the table, we see that there are 22 outcomes where at least one tails shows up. So, the experimental probability of getting at least one tails is 22/100 = 0.22.
Comparing the two probabilities, we can see that the experimental probability is significantly lower than the theoretical probability.
Therefore, the answer is (D) The experimental probability is about 1% less than the theoretical probability.
