Question

​

Answer 1

Answer:

1/10

Step-by-step explanation:

probability=10%/100%

=1/10

Answer 2

The probability that person selected at random use both is 0.1

Step-by-step explanation:

percentage of peoples use cellular phones = 75%

percentage of peoples use  PTCL = 15%

percentage of peoples use both = 10%

then

probability = $\frac{\text{number of outcome}}{\text{total number of outcome}}$

here , number of outcome = 10%

total outcome = 75%+ 15% + 10% = 100%

therefore ,

probability( person selected at random use both) = $\frac{10}{100}$ = $\frac{1}{10}$

hence , The probability that person selected at random use both is 0.1
