Answer:
$62.42
Step-by-step explanation:
1st step: Simplify the numbers first
$24.99 -------> 25
$12.99 ---------> 13
$4.49 ----------> 4
$19.95 ---------> 20
25+13+4+20= 62
cents from simplified version: 42 cents are added to the final number
$0.42+ $62.00 = $62.42
Total Cost: The four athletic items will cost $62.42 in total.
Hope this helps!!!
Answer:
you want 4 correct and 16 incorrect
there are 20 questions
each question has four answers, so
P(right answer) = 1/4
P(wrong answer) = 3/4
----
Since you want 4 correct of 20 we have a combination of 20C4
This is a binomial problem where p = 1/4, q = 3/4 and we get
(20 "choose" 4)*(probability correct)^(number correct)*(probability incorrect)^(number incorrect)
putting numbers in we get
(20c4)*(1/4)^4*(3/4)^16
This gives us
~ .189685
