User question:
user: Could you fetch the current weather data for the location with the latitude 45.4215 and longitude -75.6972? Also, I need to calculate the chances of achieving exactly 3 successes out of 5 attempts, assuming there's a 50% probability of success on each attempt.

Available functions:
name: get_weather_data
description: Fetches weather data from the Open-Meteo API for the given latitude and longitude.
parameters: type: dict
properties: coordinates: type: array
items: type: float
description: The latitude and longitude of the location.
required: coordinates
name: calc_binomial_probability
description: Calculates the probability of getting k successes in n trials.
parameters: type: dict
properties: n: type: integer
description: The number of trials.
k: type: integer
description: The number of successes.
p: type: float
description: The probability of success.
required: n
k
p

Ground-truth function call(s):
get_weather_data(coordinates=[45.4215, -75.6972])
calc_binomial_probability(n=5, k=3, p=0.5)
