Answer:
-30
Step-by-step explanation:
Joe tosses a die and gets a 3
Given that the rule that an odd number will result in a loss of 10x that number
in this case, Joe gets odd number, hence he will lose 10x that number
i.e he will get -10 x 3 = -30
The probability of choosing. a green pen is 0.25
<h3>What is probability?</h3>
Probability is the likelihood or chance that an event will occur. Mathematically;
Probability = Expected/Total outcome
If a bag has 3 blue pens, 6 red pens, and 3 green pens, then;
Total pen = 3+6+3
Total pen = 12
If a green pen is chosen, then
Pr(choosing a green pen) = 3/12
Pr(choosing a green pen) = 0.25
Hence the probability of choosing. a green pen is 0.25

Answer:
Step-by-step explanation:
Hope it is helpful...
If the first card (not replaced) is a 7, you're left with 51 cards, and the four aces are all there: you have probability 4/51 of picking an ace.
If the first card (not replaced) is an ace, you're left again with 51 cards, but these time only 3 aces are remaining in the pile: you have probability 3/51 of picking an ace.
Were the cards replaced, the information about the first card drawn would be completely meaningless, since the second pick would be a pick from a standard deck, and we'd have probability 4/52=1/13 of picking an ace.
In other words, if cards are replaced, it is like every pick is the first one, because whatever happened with the first pick has no consequences on the second.
On the other hand, if we do not replace cards, the outcome of the first pick is important, because we know that the card we picked will not be in the deck anymore.
let's firstly convert the mixed fractions to improper fractions and then divide.
