6x 34 because you have to divide and then multi
To subtract fractions, we need an lcd( lowest common denominator)
8. the lcd is 42 because it’s the smallest number that 6 and 7 are both factors of. the lcd is the bottom of the fraction
to make the denominator of (4/7) 42, we will multiply the top and bottom by 6 and we get (24/42)
to make the denominator of (3/6) 42, we will multiply the top and bottom by 7 and we get (21/42)
these two numbers now have the same denominator so we subtract them
24/42 - 21/42 = 3/42 which simplifies to 1/14
9. since these fractions already have a common denominator, we will make them mixed fractions
-5(2/7) as a mixed fraction. first multiply 5*7 which is 35. now add 2 which is 37. our mixed fraction is -37/7
-1(5/7) as a mixed fraction. multiple 1*7 which is 7. now add 5 which is 12. our mixed fraction is -12/7
now subtract (-37/7) - (12/7) and we get -49/7 which simplifies to -7
Probability of getting an order from Restaurant A or an order that is accurate is 1.21,
The events are not disjoint events.
<h3>
What is the probability?</h3>
Probability is used to calculate the odds that a random event would occur. The odds that the random event happens lie between 0 and 1.
Total number of accurate orders = 332 + 277 + 244 + 150 = 1,003
Total number of orders = 31 + 51 + 30 + 10 + 1003 = 1,125
Total number of orders from restaurant A = 332 + 31 = 363
Probability of getting an order from Restaurant A = total number of orders from restaurant A / total number of orders
363 / 1125 = 0.32
Probability that the order is accurate = number of accurate orders / total number of orders
1003 / 1125 = 0.89
Probability of getting an order from Restaurant A or an order that is accurate = 0.32 + 0.89 = 1.21
Disjoint events are events that are mutually exclusive. If one event happens, the other event cannot happen
