Step-by-step explanation:
<u><em>Q 4.</em></u> (25m + 25m) ÷ 25 sec. = <em>2 m/sec.</em>
<u><em>Q 5.</em></u> This question belongs to Physics and not Mathematics!!!
Wavelength (lambda) = Velocity (v) ÷ Frequency ( or Hz )
f = v / (lambda)
f = 3 / 2 = <em>1.5 (Hz)</em>
<u><em>Q 6.</em></u> 0.060 ÷ 2 = <em>0.030 m</em>
Get the value of the decimal:
Remember that percentages are simply the value of a decimal multiplied by 100. (From the Latin, "per centus", meaning "per 100")

Answer:
Step-by-step explanation:
We are given that a fair 6 sided die is rolled.
Let X denotes the event that an odd number
X=1, if an odd number
X=0, if an even number
Let Y indicates the event that 2,3 or 4 is rolled .
Y=0,if 1,5 or 6 rolled
Y=1 , if 2,3 or 4 rolled
We have to find P(X=0,Y=1)
It means we have to find P(2 or 4).
When X=0 and Y=1 It means we get an even number.
P(2 or 4)=P(2)+P(4)=
Hence, P(X=0,Y=1)=
