The experimental probability of getting a 6 on a number cube is StartFraction 7 over 40 EndFraction. Which is true about the event’s experimental probability?
The number 6 came up a total of 40 times.
The number 6 came up 7 times out of a total of 40 trials.
The number cube was rolled a total of 47 times.
After 7 trials, the number 6 came up 40 times.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
