The answer should be 101.
It’s C all the way bro ski
First of all, as I told you a little while ago, here is the formula
that solves ALL probability problems. Memorize this:
Probability =
(number of different successful possibilities)
divided by
(total number of all possibilities).
There are 10 keys in the bag. The total number of possible results
of pulling out one key out is 10.
3 of the keys start the car. The other 7 keys don't.
What are the 'successful' possibilities ?
The question asks for the probability of pulling keys that DON'T work.
So for this particular calculation, we're talking about choosing keys
that DON'T work. There are 7 of those.
The probability of drawing a key that doesn't work the first time is 7/10 .
Since the first key is put back in the bag and the bag is mixed, the
situation on the second draw is exactly the same as on the first one.
Thje probability of drawing a key that doesn't work the second time is 7/10 .
The probability of both events happening is (7/10)x(7/10) = 49/100 = 49% .
When you divide something by 10, yo move the decimal place one place to the left so exg
20.0/10=2.0
so divide by 1000 means move the decimal place 3 places to the left so if you had 20,000.0/1000=20.0 so
6.82/1000=0.00682
Answer:
D. The oldest is 92 youngest 49
Step-by-step explanation:
we can get the answer by pairing each of the values on the left hand side that is these values 4 5 6 7 9 with values on the right.
the first age from the top row is 49 the second is 49
from the second row it is 50 50 51 51 52 5 59
from the 3rd row 61 62 63 64 64 65 6
from the forth row t s 71 72 73 73 74 75 7
from the fifth row it is 80 81 83 87
from the sxth row it is 91 92.
each of the numbers have just written out represents age. the oldest age there is 92 whle the youngest s 49. It is simply each number under attorney paired wth stem to make a number.
