I NEED HELP QUICK!! 6 in group A saw results, 7 in group B saw results, 5 in group C saw results, 4 in group D saw results.
Part 1:
Create a two-way table for the data and find the probabilities for each group. Describe results in terms of the study.
Part 2:
What is the probability that a person saw results, given the received the power pill? What is the probability that a person saw results, given they received a placebo? Explain in terms of study.
Part 3:
What is the probability that a person received the placebo, given they did not see results? What is the probability that a person received the power pill, given that they did not see results? Explain in terms of the study.

1) Each group is composed of 10 people. They either saw results or don't saw results.

          saw results      no results   Total

A             6                        4              10  

B             7                         3              10  

C             5                         5             10  

D             4                         6              10  

Total      22                        18            40  

Probability of a group seeing results:

Group A: 6/10 = 0.6

Group B: 7/10 = 0.7

Group C: 5/10 = 0.5

Group D: 4/10 = 0.4

Probability of a group not seeing results:

Group A: 4/10 = 0.4

Group B: 3/10 = 0.3

Group C: 5/10 = 0.5

Group D: 6/10 = 0.6

2) Groups A and B  received the Power Pill.

What is the probability that a person saw results, given they received the power pill?

(6+7)/20 = 0.65

Groups C and D  received the placebo.

What is the probability that a person saw results, given they received a placebo?

(5+4)/20 = 0.45

3) What is the probability that a person received the placebo, given they did not see results?

(5+6)/18 = 0.61

What is the probability that a person received the power pill, given that they did not see results?

(3+4)/18 = 0.39

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
