5x + 25 = 7 * 22
5x + 25 = 154
5x = 154 - 25
5x = 129
x = 129/5
x = 25.8

3 envelopes having 2 red card

2 envelopes having 1 red card and 1 black card

So, No. of ways of envelope having red card = 3+2 = 5

No. of required ways of envelope having 1 red card and 1 black card = 2

So, probability of getting an envelope having 1 red card and 1 black card = $\frac{2}{5}$

Hence The chance the other card is black is $\frac{2}{5}$
