$($a$)$ Given the partial neural network as shown in Figure $2,$ is used to recognise the characters. The two inputs signals $11$ and $12$ are $1\mathrm{.}0$ and $0\mathrm{.}5$ respectively. Assume that the neurons have a Sigmoid activation function.

Caiculate the forward pass value of Q$1$ on the network.
