Answer:
0.0959
Step-by-step explanation:
There are 18+24+7+25=74 coins in the jar
Let's call
P(p) = 18/74 the probability of grabbing a penny
P(d) = 24/74 the probability of grabbing a dime
P(n) = 7/74 the probability of grabbing a nickel
P(q) = 25/74 the probability of grabbing a penny
What is the probability that you reach into the jar and randomly grab a dime and then, without replacement, a nickel?
Here we want to find P(n | d) the probability of grabbing a nickel given that you already grabbed a dime.
By the Bayes' Theorem
Now,
P(d | p) = 24/73 since there are now 73 coins and 24 dimes.
Similarly,
P(d | d) = 23/73 for you already grabbed a dime
P(d | n) = 24/73
P(d | q) =24/73
Replacing in the Bayes' formula
So
P(n | d) = 0.0959
Answer:
7.5 tank oil will be used
Step-by-step explanation:
Amount of gas used to cut one lawn (on an average) = 3/4 of a tak
Given ,
In a week , ten such lawns are cut
Hence, Total amount of gas used
= 3/4* 10
= 7.5 tank
The circumference of a circle can be found using the equation 2 π r
(2)(3.14)(4.5) = 28.26 (or 28 13/50 if you need it in fractions)
Answer:
because their are so more calculaition
Answer:
x^2 -4/3x + 4/9
Step-by-step explanation:
(x-2/3)(x-2/3)
= x^2 -2/3x -2/3x + (2/3)^2
= x^2 -4/3x + 4/9
Hope this helps! <3
