Answer:
18 times
Step-by-step explanation:
Sample space ; roll of 2 number cubes = 6^2 = 36
Sum of 4 in 2 cube rolls = 3
Probability = required outcome / Total possible outcomes
P(sum of 4) = 3 / 36 = 1 / 12
If number cube is rolled 216 times :
Probability on 1 roll * Number of rolls
(1 / 12) * 216
0.0833333 * 216
= 18
Answer:
Relative frequency of male nonparticipation is O.42
Step-by-step explanation:
Figure 1 is your partially filled frequency table.
1. Complete the table
(a) Total No
Total Yes + Total No = Total
102 + Total No = 187
Total No = 187 - 102
= 85
(b) Female No
Male No + Female No = Total No
40 + Female No = 85
Female No = 85 - 40
= 45
(c) Female Yes
Female Yes + Female No = Female Total
Female Yes + 45 = 95
Female Yes = 95 - 45
= 50
(d) Male Yes
Male Yes + Female Yes = Total Yes
Male Yes + 50 = 102
Male Yes = 102 - 50
= 52
(e) Male Total
Male Yes + Male No = Male Total
52 + 40 = Male Total
Male Total = 92
Figure 2 shows the completed table.
2. Frequency of Male No
There are 92 males, of whom 40 do not participate in an after-school activity.
The relative frequency of male nonparticipation is
40/92 = 0.43
Answer:
91
Step-by-step explanation:
0.5 in decimal form and 5/10 or 1/2 for simplified
