Answer:
Step-by-step explanation:
40% x 70% will give you the answer in percent.
.4 x .7 = .28 He has a 28/100 chance or 7/25 chance (reduced).
400-126=274
400
126
-----
0-6 can't go into so make the 0 a 6
Then make 0-2 make 0 a 10 then a 9
Then make 4 into a 3
A)
Let c be the number of right guesses.
the probability of c answers =.25 and probability of the wrong answer is 1-.25=.75
c distribution is in the parameter of (20, .25).
b) mean = 20 * .25== 5
c) p of c guess =.25 ^20 =9.095* 10 ^-13
d) p of 10 c guess =.014 or 1.4% it is not possible for him to have 10 right guess.
Answer:
B. experimental probability
Step-by-step explanation:
