The probability of Josh scoring par or above on the par-70 course is approximately 0.441 or 44.1%.
To calculate the probability of scoring par or above, we add up the probabilities for these ranges:
Probability = P(70-74) + P(75-79) + P(80-84) + P(85-89) + P(90-94) + P(95-99) + P(100 or above)
Substituting the given probabilities from the table:
Probability = 0.28 + 0.020 + 0.12 + 0.007 + 0.003 + 0.003 + 0.01
Probability = 0.441
