Answer:
The probability of rolling a number less than 10 is 0.85
Step-by-step explanation:
The probability of rolling a number less than 10 is calculated as follows;
Let x = the observation.
We're asked to solve P(x<10).
This means that we consider only numbers of observation less that 10
P(x<10) = Number of required outcome/Number of possible outcome.
Number of required outcome is summation of all observation less than 10.
This is calculated as follows;
Number of required outcome = 3+6+8+11+14+16+15+12
Number of required outcome = 85.
Number of possible outcome = summation of all observation
Number of possible outcome = 3+6+8+11+14+16+15+12+9+5+1
Number of possible outcome = 100
P(x<10) = 85/100
P(x<10) = 0.85
Hence, the probability of rolling a number less than 10 is 0.85
