The graph given below shows the distribution of biomes: (b) Mark 'grassland' and coniferous forest' biomes.

The screws produced by a certain machine were checked by examining samples of 7. The following table shows the distribution of 128 samples according to the number of defective items they contained. Fit a binomial distribution and find the expected frequencies if the chance of screw being defective is 1/2 . Also find the mean and variance of the fitted distribution.

The graph given below shows the distribution of biomes: (c) Why is 'F' located at the given position in the graph?
