1 plus 2 = 3, then u do 6/2 (3), then 3x3 = 9
we know that
The probability that "at least one" is the probability of exactly one, exactly 2, exactly 3, 4 and 5 contain salmonella.
The easiest way to solve this is to recognise that "at least one" is ALL 100% of the possibilities EXCEPT that none have salmonella.
If the probability that any one egg has 1/6 chance of salmonella
then
the probability that any one egg will not have salmonella = 5/6.
Therefore
for all 5 to not have salmonella
= (5/6)^5 = 3125 / 7776
= 0.401877 = 0.40 to 2 decimal places
REMEMBER this is the probability that NONE have salmonella
Therefore
the probability that at least one does = 1 - 0.40
= 0.60
the answer is
0.60 or 60%
If you were going to multiply those two numbers, the answer would be D, 192.
Answer:
D
Step-by-step explanation:
Answer: 7200
Step-by-step explanation: the formulae is w times l times h. So you just multiply them all together. 24x15x20= 7200
