Look at it this way:
When you flip a coin, the probability of it landing with EITHER side showing
is 100%.
This leads us to the rule ...
The sum of the probabilities of
all possible outcomes is 100%.
For a coin: (probability of heads) plus (probability of tails) = 100%.
That just says: We're 100% sure that the coin will land with either
heads or tails up.
An "honest" coin gets heads 50% of the time and tails the other 50%.
But if the coin is all bent and squashed and has a feather stuck to
one side and a wad of gum on the other side so that it comes up
heads 70% of the time, then the coin isn't 'honest'. But it still has to
land EITHER heads OR tails, so the sum of the probabilities is still 100%.
So the probability of heads is 30%.
Answer:
Step-by-step explanation:
Figure out the number of yellow beans in each bag:
Bag A: 0.5*26 = 13 beans
Bag B: 0.25*28 = 7 beans
Bag C: 0.2*30 = 6 beans
The total number of beans in the bowl: 26+28+30 = 84
Total number of yellow beans: 13+7+6 = 26
Percentage of yellow beans: 26/84 *100 = 30.9523
Rounded answer: 31%
Hi , 7/16 times 4/3 times 1/2 equals to 28/96 because 7times4 times 1 equals to 28 and 16 times 3 times 2 equals to (28/96).The answer is also equivalent to 7/24.
