An organization conducted bike race under two different categories - Boys and Girls. There were 28 participants in all. Among all of them, finally three from category 1 and two from category 2 were selected for the final race. Ravi forms two sets B and G with these participants for his college project.Let $B= \{b_1, b_2, b_3\}$ and $G= \{g_1, g_2\}$, where $B$ represents the set of Boys selected and $G$ the set of Girls selected for the final race.Based on the above information, answer the following questions:(I) How many relations are possible from $B$ to $G$ ?(II) Among all the possible relations from $B$ to $G$, how many functions can be formed from $B$ to $G$ ?(III) Let $R: B \rightarrow B$ be defined by $R = \{(x, y): x$ and $y$ are students of the same sex $\}$. Check if $R$ is an equivalence relation.OR(III) A function $f: B \rightarrow G$ be defined by $f = \{(b_1, g_1), (b_2, g_2), (b_3, g_1)\}$.Check if $f$ is bijective. Justify your answer.
