Here is a biased 5-sided spinner. When the spinner is spun, it can land on blue or on green or on purple or on red or on yellow.

The table gives information about the probability of the spinner landing on each colour.

Sophie spins the spinner once.

Work out the probability that the spinner lands on blue or on green or on purple.

Max spins the spinner 350 times.

Work out an estimate for the number of times the spinner lands on red.
