Step-by-step explanation:
There are 13 numbers here:
30, 30, 31, 32, 42, 49, 58, 58, 67, 67, 69, 78, 90.
The median number is the 7th number, which is 58.
Answer:
274.84 gallons.
Step-by-step explanation:
Divide 3,298 by 12
3298/12 =274.84
<span>1.
P(</span>at least one of the calculators is defective)=
1- P(none of the selected calculators is defective).
2.
P(none of the selected calculators is defective)
=n(ways of selecting 4 non-defective calculators)/n(total selections of 4)
3.
selecting 4 non-defective calculators can be done in C(35, 4) many ways,
where

while, the total number selections of 4 out of 18+35=53 calculators can be done in C(53, 4) many ways,

4. so, P(none of the selected calculators is defective)=

5. P(at least one of the calculators is defective)=
1- P(none of the selected calculators is defective)=1-0.18=0.82
Answer:0.82
Answer:
Zero.
Step-by-step explanation:
The empirical (or experimental ) probability is that calculated from the result of the trial.
There were no 5's thrown so the empirical probability of a 5 coming up is 0/50 or 0.
