The table shows the number if votes for the new school mascot. What percent of the students chose a mascot other than Tigers?Mascot|| Number of students

Polar bears|| 6
tigers||         14
vikings||       19
eagles||        11

Answers

The total votes are 50. If you are finding out the percentage of students that did not choose the Tigers, you would subtract the Tigers votes from the total. 50-14 =36. 36/50 would equal .72, turn that into a percent and you have 72% of students not voting for Tigers.

Josh used a standard deck of 52 cards to conduct an experiment. Half of the cards in the deck were red. The other half were black. Josh predicted that he would choose a red card in 4 out of 8 trials. When he conducted the experiment, he actually chose a red card 6 out of 8 times. Which explains the most likely reason for the discrepancy between Josh’s predicted and actual results?A.He incorrectly predicted the number of times he would choose a red card.
B.He incorrectly determined the actual number of times he chose a red card.
C.He used too few trials for the sample space.
D.He used too many trials for the sample space.

Answers

Answer: C. He used too few trials for the sample space.


Step-by-step explanation:

Given: Josh used a standard deck of 52 cards to conduct an experiment.

As half of the cards in the deck were red.

If we take sample space= 52 cards

Then probability of getting a red card=(1)/(2)

But Josh took 8 cards as sample space which is not enough for the sample space.

therefore, C. is the right answer. "He used too few trials for the sample space."

Answer:

Option C - He used too few trials for the sample space.

Step-by-step explanation:

Given: Josh used a standard deck of 52 cards to conduct an experiment. Half of the cards in the deck were red. The other half were black.

Josh predicted that he would choose a red card in 4 out of 8 trials.

When he conducted the experiment, he actually chose a red card 6 out of 8 times.

To find : Which explains the most likely reason for the discrepancy between Josh’s predicted and actual results?

Solution :

Sample space = 52 cards

As half of the cards in the deck were red.

Probability of getting a red card is (1)/(2)

He predict and conduct to choose a red card out of 8 trials which is not enough for the sample space.

Therefore, Option C is correct.

He used too few trials for the sample space.
