Perimeter = 5.35 * 4 = 21.4 cm
The probability of getting a red card is 1/2 and the probability of getting a 10 is 4/52. To find the probability of getting both a red card and a 10, multiply the two.
(1/2)(4/52) = 4/104
4/104 = 1/26
Therefore, the probability is 1/26
Let x=0.208bar or 0.20888...
1000x=208.888 and 100x=20.888 so
1000x-100x=208.888-20.888
900x=188
x=47/225
It would be; -7/9 + 2/3
= -7+6 / 9
= -1/9
In short, Your Final Answer is -1/9
Hope this helps!
