Answer:
(a) 4/9
(b) 19/27
Step-by-step explanation:
The probability of each die turning up red or not turning red are:
(a). Exactly one face up is red.
The odds of only the first die being red are:
The same odds are valid for only the second or only the third die being red. Therefore, the probability that exactly one die turns up red is:
(b). At least one face up is red.
The probability that at least one die turns up red is the sum of the probabilities of exactly one (found in the previous item), two or all dice turning up red.
Following the same logic as in the previous item, the probability that exactly two dice turn up red is:
The probability that all die turn up red is:
Thus, the probability that at least one die turns up red is:
Answer:
Irrational numbers cannot be written as a fraction, or the ratio of two whole numbers.
You would have to find a GCF (greatest common factor) and multiply it out of the radical.
ex.
= 2 x 2 x 2
when you have to multiplier numbers then you can combine two of them to take outside the radical, meaning 2x2x2
2
so would be closest to the positive 2 on the number line and 2 notches.
is an irrational number, so it might fall into 3.3 if turned into a decimal.
