Adecision maker subjectively assigned the following probabilities to the four outcomes of an experiment: p(el) = 0.10,
p(e2) = 0.15, p(e3) = 0.40, and p(ea) = 0.20
are these probability assignments valid? explain.
ple) = 0.15, ple) = 0.40, and pd.= 0.20

No

Step-by-step explanation:

If there are JUST four outcomes of the experiment, it's invalid. Because .1+.15+.4+.2=.85, which is not equal to 1.

This is beacuse since the experiment has occurred, the possibility of getting an outcome, which equals the sum of all four kinds of outcomes' possibilities, should be one.

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
