Answer: >, <, ≥, ≤
Step-by-step explanation: Any of these are clear indicators of an inequality
3+5(x-4)
= 3 + 5x - 20
= 5x - 17
3(x-6) = -12
3x - 18 = -12
3x = 6
x = 2
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%
k= 4/9 or 0.444 in decimal form.
hope this helps!
