In a sample of 30 cats from a population with a probability of 0.19 of having a coat of fur with only one color we want to determine what is the probability of choosing EXACTLY TEN cats whose coat is monocolor.

0.0272

Step-by-step explanation:

p = 0.19 q = 1 - 0.19 = 0.81

30C10 × p¹⁰ × q²⁰

= 0.02722756555

= 0.0272 (3 sf)

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
