Qr=1/2 mn = ms
mn=2 ms=12
ln^2=lm^2+mn^2 using phythagoras rule
ln^2=400
ln=20
1,500(1.02) means 1500×1.02
Ironically, buying a lot at a time is cheaper than buying bit by bit. Places like Sam's Club specialise in having bulk supplies. People might not be planning to buy bulk, but after seeing how cheap it is, they'll decide to buy more than they planned. It creates the illusion of saving money to the consumer, but in reality, they spent more just because they liked the idea of getting more product. Hope that made since! :D
Find the probability of rolling a number bigger than 4 and subtract that by 100%;
P(5)= 1/6 <-- 6 possible outcomes, 1, 2, 3, 4, 5 or 6
P(6)= 1/6
You could have rolled a 5 or 6. When the word or is used, the probabilities are added together, when and is used, they are multiplied.
(1/6)+(1/6)=2/6
1-P(5)+P(6)
=1-(2/6)
=(6/6)-(2/6)
=4/6
Therefore the probability of not rolling a number larger than 4 is 4/6 or 2/3.
Hope I helped :)
