1 answer:

4 0

We can write 499 as 499 = 500 - 1

Because it is easy to multiply 500 and 5 compare to 499 to 5.

So product of 499 * 5 = (500 - 1)*5
= 500*5 - 1*5
= 2500 -5 = 2495

So the answer is 2495.

Answer: 0.9

Step-by-step explanation:

$\mathrm{Total \ sample \ space \ $=100$} \\\mathrm{Event \ $A = \ taking \ subway \ each \ day}$$P(A)=0.85$$Event $B=$ taking taxi $\because P(B)=0.6$$$P(A \cap B)=0.55$$$

$\begin{aligned}P(A \cup B) & \Rightarrow \text { Person taking either taxi/subway } \\&=P(A)+P(B)-P(A \cap B) \\&=(0.85-0.555)+(0.6-0.55)-0.55 \\&=1.45-0.55\\&\bf{=0.9} \end{aligned}$
