| Sensory neuron | 13 | 7 | 3 |
| Motor neuron | 0 | 15 | 18 |
| Interneuron | 10 | 34 | 0 |
For 100 neurons, the table summarizes the distribution of classification and cell body diameter. One of these neurons will be selected at random. What is the probability of selecting a neuron with a cell body diameter that is less than or equal to 30 micrometers, given that it is not classified as a motor neuron? Express your answer as a decimal or fraction, not as a percent.
Fractions and decimals are both accepted. If the answer does not fit, fill the box — you may truncate or round.
